Until recently, insects and their allies were seen
as being of economic importance merely as an annoyance
or menace to man and his flocks and herds, or injurious
to his crops. But there has since sprung into prominence
(5) the knowledge that in a more insidious manner they may
be the enemy of mankind: that they may be among the most
important of the disseminators of disease. This
knowledge has revolutionized our methods of control of
certain diseases, and has become an important weapon in
(10) the fight for the conservation of health.
Great movements and discoveries do not arise
suddenly; centuries ago the possibility that insects
were concerned with disease was suggested, and from time
to time there have been keen suggestions and hypotheses
(15) along this line. One of the earliest is by the Italian
physician, Mercurialis (1530-1607), during a period when
Europe was being ravaged by the plague: "There can be no
doubt that flies feed on the internal secretions of the
diseased and dying, then, flying away, they deposit
(20) their excretions on the food in neighboring dwellings,
and persons who eat of it are thus infected."
More worthy of consideration is the approval given
to Mercurialis's view by the German Jesuit Athanasius
Kircher in 1658, who attributed the production of
(25) disease to bacteria and formulated, albeit vaguely, a
theory of the animate nature of contagion. But it took
two and a half centuries of scientific advancement to
accumulate the facts to prove his hypothesis.
In 1848, Dr. Josiah Nott published an article on
(30) the cause of yellow fever, in which he presented
"reasons for supposing its specific cause to exist in
some form of insect life." Curiously, the bearing of
Nott's work on present-day ideas of the insect
transmission of disease has been overrated: written
(35) before the discoveries of Louis Pasteur and the
recognition of micro-organisms as factors in disease
propagation, his article refutes the theory of
"malarial" origin of "all the fevers of hot climates,"
but he uses the term "insect" too broadly for our
(40) present purposes. Almost contemporaneously, the French
physician Louis Daniel Beauperthuy argued that yellow
fever and others were transmitted by mosquitoes. He not
only discussed the role of mosquitoes in the
transmission of disease, but also taught that houseflies
(45) scatter pathogenic organisms.
It can be inferred from the passage that Louis Pasteur:
A] Developed a method to eliminate dangerous micro-organismsnull
B] Made important headway in the field of bacteriologynull
C] Discovered his sterilization technique almost by accidentnull
D] Made use of a more nuanced definition of the classification "insect"
null
E] Defined the role of micro-organisms in disease propagation
Which of the following might still spur further discoveries in the field discussed by the author of the passage?
A] Innovations in pasteurization technologynull
B] Identification of several new species of mosquitonull
C] Pinpointing of a strain of vaccine-resistant bacterianull
D] Outbreak of a heretofore undocumented contagious diseaseYour answer was correct!null
E] Spread of a new strain of disease across multiple continents
The tone in which this passage is written can be said to manifest what attitude on the part of the author?
A] IndifferenceYour answer was incorrectnull
B] Impatiencenull
C] Approvalnull
D] Admirationnull
